IMPROVEMENT IN LOOM-TEMPLES.

Specification forming part of Letters Patent No. 190,783, dated May 15,1877; application filed April 2, 1877.

To all whom it may concern:

Be it known that I, CHRISTIAN H. SOHLAF, of Rockville,in the county ofTolland and State of Connecticut, have invented a new and usefulImprovement in Loom-Temples, of which the following is a specification:

Figure 1 is a top view of my improved tenter. Fig. 2 is a side view ofthe same. Fig. 3 is a detail section of one of the catches, takenthrough the line a; a, Fig. 1. Fig. 4 is a detail face view of one ofthe movable jaws. Fig. 5 is a View illustrating the use of the device.

Similar letters of reference indicate corresponding parts.

The object of this invention is to furnish an improved device forstretching the cloth while being woven, and which shall be soconstructed as to adjust itself as the cloth is being woven and carried.forward to the clothbeam.

The invention consists in the combination of the slotted plate, theadjustable block, the pivoted stretchers provided with the catches,

"and the foot, and connected together by the pin and slot, the spiralspring, and the arm, as hereinafter fully described.

A is the plate of the device, which is placed edgewise against the innerside of the breastbeam of the loom, and has ears formed upon its ends toreceive the screws or bolts by which it is secured to said breastbeam.

The plate A is slotted longitudinally to receive the flange formed uponthe block B, and through which the bolt passes that secures the block Bin place upon the plate A, so that by loosening the nut of the saidbolt, the block B may he slid out and in to adjust the device to wideror narrower cloth.

To the upper side of the inner end of the block B is pivoted the end ofa bar or lever, 0, called by me a stretcher, which is curved outward,forward, and inward, and has its end forked.

To the lower side of the end of the stretcher C is attached the lower orstationary jaw D of the catch, the upper or movable jaw D of which ispivoted to and between the prongs of the end of the stretcher C.

Upon the face of the stationary jaw D are formed two or more teeth,corrugations, or shoulders, and upon the face of the pivoted jaw D areformed two or more teeth, inclined toward the stretcher C, so that thesaid jaws may grasp and hold the cloth when they move outward, but mayslide over it when they move inward.

To the block B, at a little distance from the end of the stretcher C, ispivoted a sec ond stretcher, E, which is curved outward, forward, andinward, and its end is provided with a catch, F, similar to the catch D.

The forward end of the stretcher E projects forward and inward, and hasa foot, I, formed upon it. The inwardly-projecting end of the stretcherE crosses the stretcher O, and has a pin, 0, attached to it, whichenters a short slot, 0, in the stretcher C, so that the forward andbackward movement of the stretcher E may move the stretcher C backwardand forward.

To the bend of the stretcher E is attached the end of a spiral spring,Gr, the other end of which is attached adjust-ably to the end of an arm,H, formed upon or attached to the block B, so that the tension of thespring G, and consequently the strain upon the cloth, may be regulatedas required. Two of these devices are attached to the breast-beam, oneat each edge of the web, as shown in Fig. 5.

lVith this construction, as the lathe swings forward to drive awoof-thread to its place, it strikes the foot I of the stretcher E, andoperates the said stretcher E, to move its catch forward to take anotherhold. The forward movement of the stretcher E moves the strecher Coutward, causing its catch D to grasp the cloth and hold it till thecatch F of the stretcher E has again grasped the said cloth. As thelathe swings back, the spiral spring G again stretches and holds thecloth.

Having thus described my invention, claim as new and desire to secure byLetters Patcut- The combination of the slotted plate A, the adjustableblock B, the pivoted stretchers C E, provided with the catches D F, andthe foot 1, and connected together by the pin and slot 6 c, the spiralspring G, and the arm H, substantially as herein shown and described.
